<ul><li> As of 2020-11-20, the latest release of Oracle Developer Studio <a rel="nofollow" class="external text" href="https://www.oracle.com/application-development/technologies/developerstudio-component-matrix.html">is 12.6</a>. Its <a rel="nofollow" class="external text" href="https://docs.oracle.com/cd/E77782_01/html/E77789/bkaje.html">documentation</a> does not mention C++17.
</li><li> Cray compiler may have support for some features earlier than 11.0. That version is when it became a derivative of Clang, gaining all of the attendant language feature support of the base compiler.
